Orbit and dynamics
Between its closest point (0.955 AU) and its farthest (1.977 AU), the heliocentric distance changes by 1.022 AU over every revolution.
One full revolution takes 1.78 yr (648 days), computed from the semi-major axis of 1.466 AU.
An eccentricity of 0.348 makes the orbit moderately elongated.
The orbital plane is tilted 9.17° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 35.4 km/s at perihelion and falls to 17.1 km/s at aphelion.
Because q < 1 AU and Q > 1 AU, this orbit geometrically intersects the region of Earth's orbit.
Size and surface
The measured diameter is 0.12 km, a value from direct size determination rather than from brightness alone.
Its geometric albedo of 0.099 indicates a very dark, carbonaceous-type surface.
Observation record and orbit quality
Astrometry from 40 individual observations underpins this orbit; the fit leaves an RMS residual of 0.3147 arcseconds.
Condition code U = 3 indicates a moderately constrained orbit; predictions decades ahead still carry noticeable uncertainty.
About these computed values
Orbital periods, perihelion and aphelion speeds, and diameter estimates on this page are computed by SpaceAtlas from the JPL SBDB orbital elements. They are derived quantities, not values copied from the source catalogue.
